Parts/kits listed are now obsolete and are no longer serviceable through Bendix.

IR CAMERA WINDOW

Maintaining

The IR camera window, a 1.3 mm thick silicon disk, is an optical element and should be cleaned when it becomes dirty or filled with debris. Dirt and debris can affect the IR camera performance.

To clean the window, use a soft, damp cloth moistened with window cleaning solution. Shop rags and paper towels will scratch optical surfaces.

NOTE: The IR camera heater cannot melt large amounts of packed snow in the window area. It is recommended that the snow be removed manually prior to system operation. When cleaning ice or snow from the IR camera, use a commercially available spray deicer; do not use scrapers or sharp instruments that may scratch or break the window.

Replacing

If the window cracks or breaks, it must be replaced.

1.Unlock the IR camera assembly by turning the two IR camera aiming adjusters and the standoff pivot assembly 1/4 turn counterclockwise.

2.Remove the IR camera from the IR camera bracket to gain easier access to the connectors.

3.Disconnect the 6-pin IR camera connector and the 2-pin window heater connection of the IR camera harness from the IR camera.

4.Lay the IR camera face-up for easy access to the bezel retaining plug. Refer to Figure 26.

5.Remove the bezel retaining plug.

6.Turn the bezel heater assembly 1/4 turn counterclockwise, until it separates from the IR camera.

7.Replace the damaged window and seal.

NOTE: The replacement window is treated with a black scratch-resistant coating on one side only. The side that appears black must face the environment.

NOTE: If the area between the IR camera window and IR camera lens is contaminated because of a damaged seal or window, carefully remove the contamination. If a window cleaning solvent is used to clean the area, be sure to remove all of the moisture from the sealed cavity before assembling the o-ring seal and window. Moisture remaining in the sealed area will affect the performance of the IR camera.

NOTE: Use care when removing shards of glass.

8.Turn the bezel heater assembly 1/4 turn clockwise to reattach it to the IR camera. Note: Ensure the window is positioned correctly or it can be damaged when installing the bezel.

9.Lock the bezel heater assembly in place with the bezel retention plug.

10.Plug the 2-pin connector of the IR camera harness into the window heater. Refer to Figure 24 on page 12.

11.Plug the 6-pin connector of the IR camera harness into the IR camera connection. Refer to Figure 24 on page 12.

12.Position the IR camera onto the factory-installed aiming assemblies.

13.Rotate the pivot locks on the end of the aiming assemblies 1/4 turn clockwise, using the aiming adjuster tool. This will lock the IR camera in position.

14.Aim and adjust the IR camera. Refer to Aiming the IR Camera on pages 21 and 22.
